Hi , is there any mandatory Training requirement to appear for 1Z0-511 (Oracle E-Business Suite R12 Project Essentials) certification? Also please suggest if any good resource available for reference.
No. There is no training requirement to become Oracle E-Business Suite R12 Project Certified Implementation Specialist. The link the the certification is below and shows no training requirement:
Oracle E-Business Suite R12 Project Certified Implementation Specialist
I can't suggest materials. Oracle Apps is not something I have experience with.
